TamTam instrument hotkeys may not map properly to non-US keyboards

Description

When TamTam is started up fresh (rather than from the Journal), it has three default instruments and rhythms set up; by default the 9, 0 and / keys are labeled as being toggle keys for the three instruments, / being used for the drum beat.

On non-US keyboards where the / key is not the one next to the right-hand shift key (such as the Spanish keyboard, where it is -/_), hitting the / key on that keyboard does not toggle the drum playback, but instead the key next to the right-hand shift key toggles the playback.

At a guess, this is caused by TamTamEdit looking for the location of the keypress rather than the value sent by the keypress.
